Patent JP-S5576420-A (JP)
Title: Bus driving system
Inventor: KISHI KENICHI
IPC: G06F3/00
Filed: 1978-12-01
Abstract: PURPOSE: To realize a bus driving system which is free from occurrence of the switching noise and capable of a high-speed operation by varying the constant current value of the constant current circuit which constitutes the emitter common logic ECL circuit of the side where the signals are transmitted.  
     CONSTITUTION: In case the ECL circuit is used as the reception side, the H-level signal is applied to input terminal C of L-level conversion control part LLC. As a result, the potential increases at point S, and accordingly the potential at point R increases. Thus current I 0  of constant current circuit CC increases. With increment of current I 0 , current I 1  increases, and thus potential VT at point T lowers to lower the conductivity of transistor Tre comprising the emitter follower. Thus the output voltage at point PS decreases. On the contrary, when the signals are transmitted, the L-level signal is applied to terminal C to feature the opposite action to the above. Thus the potential increases at point PS. As a result, the L-level of the ECL circuit at the reception side can always be set lower than the L-level of the ECL circuit at the transmission side. In such way, the noise is never caused at the switching time, thus preventing the low-speed operation of the circuit.
